What is DNC Scrubbing?
DNC scrubbing (Do Not Call scrubbing) is the process of comparing your outbound call list against the National Do Not Call Registry maintained by the Federal Trade Commission (FTC). The registry contains phone numbers of consumers who have opted out of receiving telemarketing calls.
Under the Telephone Consumer Protection Act (TCPA) and the Telemarketing Sales Rule (TSR), businesses making telemarketing calls must scrub their call lists against the National DNC Registry at least every 31 days. Failure to comply can result in fines ranging from $500 to $53,088 per violation.
